Severance Benefits

Severance Benefits

Subject to Mitigation, you will receive the following severance benefits, as your sole severance benefits:

In the event that the Company terminates your employment without Cause (and other than as a result of your death or Disability) or you resign your employment for Good Reason and such termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)), and subject to your delivery to the Company of an executed release and waiver of claims in the form as the Company may require (the “Release”), within the time period set forth therein, but in no event later than forty-five days following your termination, and permitting such Release to become effective in accordance with its terms, then you will receive the following severance benefits, as your sole severance benefits (collectively, the “Severance Benefits”):

(i) 12 months of your Base Compensation in effect as of the termination date (ignoring any reduction in salary that is the basis for a Good Reason Resignation), paid in the form of salary continuation for 12 months less required deductions and withholdings, paid according to the normal payroll practice of the Company and commencing with the first regular payroll date following the effectiveness of the Release;

(ii) a lump sum cash severance payment in an amount equal to the amount of any annual bonus that you received in the 12-month period preceding the termination of your employment (unless your service terminates between the time a bonus is approved by the Board and paid to you, in which case the payment shall equal the amount of the annual bonus that was approved but not paid), less required deductions and withholdings, paid on the first regular payroll date following the effectiveness of the Release;

(iii) provided that you timely and accurately elect to continue your health insurance benefits under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company shall pay the COBRA premiums for you and your qualified beneficiaries until the earliest of (i) 12 months following the termination of your employment, (ii) the expiration of your continuation coverage under COBRA and any applicable state COBRA-like statute that provides mandated continuation coverage or (iii) the date you become eligible for health insurance benefits of a subsequent employer. You agree to immediately notify the Company in writing of any such eligibility. For purposes of this Section references to COBRA premiums shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan; and

(iv) you shall receive accelerated vesting of all unvested Stock Awards in accordance with each Stock Award vesting schedule as if you had remained employed by the Company for an additional 12 months from the date of termination.

The Severance Benefits will cease in the event of your death and shall expire on the fourth annual anniversary of the commencement of your employment with the Company; provided, however, that such rights shall automatically renew for successive one year periods unless the Company provides written notice to you at least 30 days prior to the next scheduled expiration date that such rights will not be renewed.

Change of Control Severance Benefits

If, on or within the 24 months following a Change of Control, the Company terminates your employment without Cause (and other than as a result of your death or Disability) or you resign your employment for Good Reason and such termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)), and subject to your delivery to the Company of an executed Release, within the time period set forth therein, but in no event later than forty-five days following your termination, and permitting such Release to become effective in accordance with its terms, then you will receive the following change of control severance benefits, as your sole severance benefits (collectively, the “Change of Control Severance Benefits”):

(i) a lump sum cash severance payment in an amount equal to 18 months of your Base Compensation in effect as of the termination date (ignoring any reduction in salary that is the basis for a Good Reason Resignation), less required deductions and withholdings, paid on the first regular payroll date following the effectiveness of the Release;

(ii) a lump sum cash severance payment in an amount equal to the amount of any annual bonus that you received in the 12-month period preceding the termination of your employment (unless your service terminates between the time a bonus is approved by the Board and paid to you, in which case the payment shall equal the amount of the annual bonus that was approved but not paid), less required deductions and withholdings, paid on the first regular payroll date following the effectiveness of the Release;

(iii) provided that you timely and accurately elect to continue your health insurance benefits under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company shall pay the COBRA premiums for you and your qualified beneficiaries until the earliest of (i) 12 months following the termination of your employment, (ii) the expiration of your continuation coverage under COBRA and any applicable state COBRA-like statute that provides mandated continuation coverage or (iii) the date you become eligible for health insurance benefits of a subsequent employer. You agree to immediately notify the Company in writing of any such eligibility. For purposes of this Section references to COBRA premiums shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan; and

(iv) all Stock Awards shall vest immediately.

Parachute Payments

Anything in this Agreement to the contrary notwithstanding, if any payment or benefit you would receive from the Company pursuant to this Agreement or otherwise (a “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion of the Payment, up to and including the total Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order: reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. If acceleration of vesting of stock award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of the your stock awards.

The Company shall appoint a nationally recognized independent accounting firm to make the determinations required hereunder, which accounting firm shall not then be serving as accountant or auditor for the individual, entity or group that effected the Change of Control. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder.

The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Company and you within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by the Company or you) or such other time as requested by the Company or you. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish the Company and you with an opinion reasonably acceptable to you that no Excise Tax will be imposed with respect to such Payment. The Company shall be entitled to rely upon the accounting firm’s determinations, which shall be final and binding on all persons.

Section 409A

It is intended that each installment of the Severance Benefits or Change of Control Severance Benefits is a separate “payment” for purposes Section 1.409A-2(b)(2)(i) of the Treasury Regulations. For the avoidance of doubt, it is intended that payments of the Severance Benefits or Change of Control Severance Benefits satisfy, to the greatest extent possible, the exemptions from the application of Section 409A provided under Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9) of the Treasury Regulations. However, if the Company determines that the Severance Benefits or Change of Control Severance Benefits constitute “deferred compensation” under Section 409A and you are, on your separation from service, a “specified employee” of the Company (as such term is defined in Section 409A(a)(2)(B)(i) of the Code) then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of the payment of the Severance Benefits or Change of Control Severance Benefits shall be delayed so that on the earlier to occur of: (i) the date that is six months and one day after your separation from service and (ii) the date of your death (such applicable date, the “Specified Employee Initial Payment Date”), the Company shall (A) pay to you a lump sum amount equal to the sum of the Severance Benefits or Change of Control Severance Benefits that you

would otherwise have received through the Specified Employee Initial Payment Date if the commencement of the payment of the Severance Benefits or Change of Control Severance Benefits had not been so delayed pursuant to this paragraph and (B) commence paying the balance of the Severance Benefits or Change of Control Severance Benefits in accordance with the applicable payment schedules set forth in this Agreement.

You will apply your best efforts to seek and obtain other employment or consulting engagements, whether on a full- or part-time basis during such 12-month period in order to mitigate the Company’s obligations. At reasonable intervals, you will report to Vical with respect to such efforts and any compensation earned during such 12-month period.

securities eligible to vote for the election of directors; except that any change in the relative beneficial ownership of the Company’s securities by any person resulting solely from a reduction in the aggregate number of outstanding shares of the Company’s stock, and any decrease thereafter in such person’s ownership of securities, shall be disregarded until such person increases in any manner, directly or indirectly, such person’s beneficial ownership of any securities of the Company.

6. Stock Awards shall mean all stock options, restricted stock, and other equity awards granted pursuant to the Company’s stock option and equity incentive award plans or agreements and any shares of Company stock issued upon exercise thereof.
